Improved school-desk



than gana CALVIN W. SHERWOOI)l OF CHICAGO, ILLINOIS.

Lette-rs Patent No. 101,670, (lated April 5, 1870.

IMPRovED SCHOOL-DESK The Schedule referred to in these Letters Patent and making part of the same.

I, CALVIN W. Sunnwoon, of the city of Chicago, in'the county of Cook and State of Illinois, have in-` vented certain new and useful Improvements in School- Desks, of which the following is a full description, reference being had to the accompanying drawingsv mak# ing a part of this specification, in which- Figure 1 is a perspective,

Figure 2, an end view.

My improvement relates to that class of school desks in which a desk and seat are supported by av single frame or pair of standards, in such a manner that the desk is used by one pupil and the seat byv another, the back ofthe seat forming the front of the desk.

In the use of such desks aud seats, it `has been found that the pupil occupying the seat, by leaning against the front of the desk, which forms the back of the seat', jars and shakes the desk, frequently to the great inconvenience and annoyance of the pupil using the desk; andwhere two pupils occupy the same seat,

The standards are made of east-iron, but may be n'iade of wood or other suitable material,

The `parts a b E constitute my improvement, a and b being two bars`A or supports located a little distance from the back D, and cast with and as a part of the. standards; or they can be made from wrought iron or other suitable material, and securely fastened to the standards, in the proper place, in any suitable manner. They might, when made separate, be forked at the bottom, and secured to the standards by means of nuts and bolts; or that part of thc standards to'which the bars are attached could be cast somewhat heavier than usual, with a hole for the reception of the lower endv of the bar, which could then be held in place by a single nut on the lower end thereof.

Eis a board secured to the bars a b, forming an independent back for the seat. This back, being placed a short distance from the front I) of the desk, furnishes a back for the pupils occupying the seat B to lean against, and thus prevents the jarring and shaking of the desk, the back E receiving the shock occasioned by the movements of the pupil, instead of the desk, as is the case with desks not having my improvement.

IVhat I claim as new is as follows:

The independent back, composed of the parts a b E,conuected witha school-desk and seat, substantially as specied.
